[PATCH net-next v6 5/7] net/sched: act_ct: set ctinfo in meta action depending on ct state

Currently tcf_ct_flow_table_fill_actions() function assumes that only
established connections can be offloaded and always sets ctinfo to either
IP_CT_ESTABLISHED or IP_CT_ESTABLISHED_REPLY strictly based on direction
without checking actual connection state. To enable UDP NEW connection
offload set the ctinfo, metadata cookie and NF_FLOW_HW_ESTABLISHED
flow_offload flags bit based on ct->status value.

Notes:
    Changes V5 -> V6:
    
    - Update to use flow_offload NF_FLOW_HW_ESTABLISHED bit instead of
    ext_data pointer.
